Technical Field

The present invention relates to a method of manufacturing a printed circuit board having test points and a printed circuit board manufactured thereby, and more particularly, to a method of manufacturing a printed circuit board having test points and a printed circuit board manufactured thereby as follows: in the method, a test point and a pad are formed on a printed circuit board, and then the test point and the pad are electrically connected to each other, thereby enabling to form pads having a spacing smaller than that in the related art, facilitating miniaturization of the printed circuit board by mounting a connector smaller than that in the related art on the printed circuit board, and using the test point formed in advance as it is even after the used connector is removed from the printed circuit board.

Background

A printed circuit board is an area in which components of an electronic circuit are mounted, and is generally manufactured by a printing method of printing wiring along a circuit pattern and etching the remaining portion except for the printed area.

The printed circuit board may have various problems such as defects of components themselves mounted on the printed circuit board, improper mounting of the components, or inaccurate patterns printed on the printed circuit board.

A specific test portion having the measurement terminals led out to repair and inspect the printed circuit board to solve the above problem is referred to as a test point.

In the related art process, instead of separately forming test points on the printed circuit board, after hole-type connectors are used on the pads formed on the printed circuit board, holes of the pads remaining where the connectors are removed are electrically connected to a jig and used as test points to perform another process, such as testing.

Meanwhile, when the connector used in the printed circuit board occupies a large space of the printed circuit board, the size of the printed circuit board itself is inevitably increased. When the size of the printed circuit board is reduced using a connector smaller than the related art, the holes remaining after removing the connector do not match the pitch interval of the jig in the related art, and thus cannot be used as test points. Therefore, in order to use the holes as test points, it is necessary to separately produce jigs fitted to pitch intervals of connectors smaller than the related art. However, in this case, since holes between pins of a jig electrically connected to the test point become too close, the jig is damaged when punching is performed at the time of manufacturing the jig, and since the thickness of the pins of the jig is reduced, there is a problem that the jig is warped or damaged at the time of performing the test. In addition, when a connector smaller than the related art is used, the related art jig cannot be used. Therefore, only when test points matching the pitch size of the jig in the related art are separately formed in the vicinity of the connector, the test points can be used by using the jig in the related art even after the connector is removed. In this case, it is not meaningful to miniaturize the connector, because the space of the printed circuit board occupied by the connector smaller than the prior art and the test point matching the pitch size of the jig in the prior art does not differ greatly from the space of the printed circuit board occupied by the connector in the prior art. Therefore, in the case of a task requiring mass production, a connector smaller than that of the related art cannot be used.

Therefore, in order to solve the problem that a connector smaller than the connector of the related art cannot be used in a case where a task requiring a mass production process is required, the present inventors have developed a method of manufacturing a printed circuit board having test points, in which the test points and pads are formed on the printed circuit board and then electrically connected to each other, so that pads having a smaller pitch interval than that in the related art can be formed, miniaturization of the printed circuit board is facilitated by mounting a connector smaller than the connector in the related art on the printed circuit board, and the test points formed in advance are used as they are even after the used connector is removed from the printed circuit board, and a printed circuit board manufactured thereby.

Detailed Description

Hereinafter, exemplary embodiments will be presented to aid in understanding the present invention. However, the following exemplary embodiments are provided only for easier understanding of the present invention, and the contents of the present invention are not limited by the exemplary embodiments.

Fig. 1 is a flowchart sequentially showing a process for manufacturing a printed circuit board having test points according to an exemplary embodiment of the present invention.

Referring to fig. 1, first, one or more test points having a first pitch interval are formed at an upper side of a printed circuit board (S101).

Here, the pitch interval may mean: a distance of a space when things having the same shape are repeatedly arranged at the same space. For example, the "pitch" may mean a distance between the teeth of a serrated wheel or a distance between the threads of a screw. Further, the "spacing" may be a distance between test points, a distance between pads, a distance between holes of a connector, a distance between pins of an adapter, or the like.

According to an exemplary embodiment, the first pitch for test points having the minimum pitch formed according to the minimum diameter of the test points and the minimum distance between the test points may correspond to a pitch of 1.6 mm. The first pitch spacing may vary depending on the minimum diameter of the test points and the minimum spacing between the test points. For example, when the minimum diameter of the test points is 1.2mm and the minimum spacing is 0.4mm, the first pitch spacing of the test points is 1.6 mm. Further, when a jig having a minimum pitch interval is used, the first pitch may correspond to a pitch of 1.6 mm. After removing the connector used in the printed circuit board in the development step of the printed circuit board, additional processing is performed by electrically connecting the jig to the test point so that the first pitch interval may be changed according to the pitch interval of the jig having the smallest pitch interval. The jig having the minimum pitch interval may mean a jig having the minimum pitch interval as follows: when the jig is manufactured, the jig is prevented from being damaged when the jig is perforated, or the jig is prevented from warping or being damaged when a test is performed due to the reduction of the thickness of the pins of the jig. Further, the one or more test points may be one or more specific test parts for repairing and inspecting a printed circuit board, a component or a pattern of the printed circuit board, or the like. The one or more test points may be arranged to: the first pitch interval is maintained while being staggered in the diagonal direction, or may be arranged to be positioned in a row on one or more same straight lines. The printed circuit board may be a printed circuit board applied in the field of a Battery Management System (BMS) for an automobile.

Here, "diagonal direction" may mean a line that is not perpendicular to a plane or a straight line. For example, a diagonal direction may refer to a direction: in this direction, a plurality of test points positioned to have a first pitch interval are arranged at regular intervals and are connected along a line repeatedly bent at a predetermined angle (for example, 60 degrees) instead of being located on the same straight line, and the test points arranged in a diagonal direction may have the same shape, such as an embossed shape, on upper and lower sides or left and right sides.

Further, a configuration in which one or more test points are arranged in a column positioned on one or more same straight lines may mean a configuration in which: in this case, the test points are formed at a first distance apart and lie in particular on a straight line, and the test points which are arranged in this way so as to be positioned on a straight line can have the same shape, for example a pattern (d).

Next, one or more pads having a second pitch interval are formed at positions adjacent to the one or more test points (S102).

Here, "adjacent" may mean side-by-side or close to each other, or having boundaries that contact each other.

The second pitch may have a pitch interval smaller than the first pitch so that a connector having a minimum size is mounted on the printed circuit board. In terms of process technology, there is a limit in minimizing the pitch interval of the jigs, and thus, the minimum pitch interval of the test points formed on the printed circuit board may be determined according to the minimum pitch interval of the jigs. For example, when the minimum pitch interval of the jig is a pitch of 1.6mm, the minimum pitch interval of the test points may also be a pitch of 1.6 mm. In the related art process, instead of separately forming test points on the printed circuit board, after a hole type connector is used on the pads formed on the printed circuit board, holes from which the pads remaining by the connector are removed are electrically connected to a jig and used as test points to perform another process such as testing. As described above, the minimum pitch interval of the jig is associated with the pitch interval of the pads, and as a result, a connector having an interval equal to or smaller than the pitch interval of the jig cannot be used. However, by forming one or more test points on the printed circuit board and electrically connecting the one or more test points with one or more pads, the separately formed test points are used after removing the connector, so that the pitch interval of the pads can be independent of the pitch interval of the jig, and as a result, a connector having an interval equal to or less than the minimum pitch interval of the jig can be used. Further, in the case where the first pitch of the test points is formed to have a pitch interval of 1.6mm and the second pitch of the pads is formed to have a pitch of 2.54mm larger than the first pitch or a pitch of 1.27mm smaller than the first pitch, the area occupied by the connectors having a pitch of 2.54mm is about three times that of the connectors having a pitch of 1.27mm according to a comparison result of the areas of the connectors used in the printed circuit board after the connectors are connected to the pads, so that the second pitch having a pitch interval smaller than the first pitch can effectively achieve the purpose of miniaturization of the printed circuit board. For example, a second pitch for using a smaller connector in a printed circuit board than in the prior art may correspond to a pitch of 1mm to 1.27 mm.

Further, the one or more pads may mean one or more metal plate films which are coated around a hole in which a part is inserted when a component or the like mounted on a printed circuit board is inserted into the printed circuit board, which may be used for attachment or electrical connection of the printed circuit board and the component or the like, and may also be used for test purposes or the like.

Next, after steps S101 and S102, the one or more test points are electrically connected to the one or more pads, respectively (S103).

Here, "electrically connected" may mean that the connected elements or devices or the like are allowed to transmit electrical signals. Further, "transmitting an electric signal" may mean that necessary software or the like can be downloaded or uploaded to the printed circuit board. Further, "transmitting an electrical signal" may mean being able to determine whether a component or the like mounted on a printed circuit board has a defect, whether the component or the like is properly mounted on the printed circuit board, whether a pattern is accurately printed on the printed circuit board, or the like.

Next, the pads are electrically connected with the connectors having the pin interval of the second pitch (S104).

Here, the connector may refer to a component connected to a pad and a test point of a printed circuit board. The connector allows a device or component or the like connected to the connector and the printed circuit board to transmit electrical signals to each other. The necessary software can be downloaded or uploaded to the printed circuit board using electrical signals transmitted through the component to connect to other components or devices. In addition, it is possible to determine whether or not a component or the like mounted on the printed circuit board has a defect, whether or not the component or the like is properly mounted, whether or not a pattern is accurately printed on the printed circuit board, or the like.

Next, the connector is mounted on the printed circuit board (S105).

Here, the connector may be mounted so as to be subsequently removable from the printed circuit board. Such a configuration in which the "connector is mounted to be removable" may mean, for example, a configuration in which it is easy to subsequently remove the connector due to weak coupling during welding, and means: a mounting portion or a temporary mounting portion is provided at a mounting position of the connector so that the connector is fixed on the printed circuit board.

Next, a step of developing and testing the printed circuit board is performed (S106).

Here, the developing and testing step may be a step of downloading or uploading necessary software or the like to the printed circuit board. In addition, the developing and testing step may be a step of determining whether a component or the like mounted on the printed circuit board has a defect, whether the component or the like is properly mounted, whether a pattern is accurately printed on the printed circuit board, or the like.

Next, when the step of developing and testing the printed circuit board is completed, the connector is removed, and when the step of developing and testing is not completed, the step of developing and testing is performed again on the printed circuit board (S107).

Here, the configuration of removing the connector may mean a configuration of returning the printed circuit board to a state before the connector is mounted without damaging test points and pads, printed circuit patterns, components, and the like on the printed circuit board. In addition, even after the connector is removed, since the test points and the pads are electrically connected, the printed circuit board can be tested, and software or the like can be downloaded or uploaded to the printed circuit board by using a jig according to the pitch size of the test points. Further, it is possible to determine whether a component or the like mounted on the printed circuit board has a defect, whether the component or the like is properly mounted, whether a pattern is accurately printed on the printed circuit board, or the like.

Here, the jig may be a device that: after removing the connector on the printed circuit board, the jig is electrically connected to the one or more test points to download or upload necessary software or the like to the printed circuit board, test the printed circuit board, or the like.

Next, the configuration of the printed circuit board manufactured by the above-described manufacturing process will be described in more detail with reference to fig. 2 to 4.

Fig. 2 is a view showing test points arranged to be staggered in a diagonal direction on a printed circuit board according to an exemplary embodiment of the present invention, fig. 3 is a view showing test points arranged in a straight direction on a printed circuit board according to an exemplary embodiment of the present invention, and fig. 4 is a view schematically showing a connector mounted on a printed circuit board according to an exemplary embodiment of the present invention.

Referring to fig. 2 to 4, a printed circuit board 1 having a test point according to an exemplary embodiment of the present invention may generally include: one or more test points 100; one or more pads 110; and a connecting portion 120. Further, the exemplary embodiment may additionally include a connector 130.

The printed circuit board 1 is a board in which metal wires are thinly printed, and may mean a board in which: which is provided so that various components such as semiconductors, capacitors, and resistors can be inserted into a printed circuit board, thereby serving to connect the components and the like through metal wires.

The one or more test points 100 may be one or more specific test sections for repairing and inspecting the printed circuit board 1. In addition, the one or more test points 100 may be electrically connected to one or more pads 110 described below through a connection portion 120. Furthermore, even after performing the steps of developing and testing the printed circuit board and removing the connector 130, the one or more test points 100 may be used to download or upload necessary software or the like to the printed circuit board 1 and test the printed circuit board 1.

The one or more pads 110 may be used for attachment or electrical connection of the printed circuit board 1 and components and the like, and may also be used for testing and the like.

The connection portion 120 may be used to electrically connect one or more test points 100 to one or more pads 110. The one or more test points 100 may be electrically connected to the one or more pads 110 through the connection part 120, thereby transmitting an electrical signal to the printed circuit board 1.

The connector 130 is connected to one or more pads 110 of the printed circuit board 1 and one or more test points 100 for transmitting electrical signals between the printed circuit board 1 and other devices connected to the connector.

Referring to fig. 2, the one or more test points 100 may be arranged to be staggered in a diagonal direction while maintaining a first pitch interval, and may be electrically connected to one or more pads 110 formed to have a second pitch interval at positions adjacent to the one or more test points 100 through a connection portion 120. Here, the second pitch may have a pitch interval smaller than the first pitch. For example, the first pitch may correspond to a pitch of 1.6mm, and the second pitch may correspond to a pitch of 1mm to 1.27 mm.

Referring to fig. 3, the one or more test points 100 may be arranged to be positioned in a column on one or more same straight lines while maintaining a first pitch interval, and may be electrically connected to one or more pads 110 formed to have a second pitch interval at a position adjacent to the one or more test points 100 through a connection portion 120.

Referring to fig. 4, after a connection portion through which one or more test points are electrically connected to one or more pads is formed on the printed circuit board 1, a connector 130 electrically connected to the one or more pads may be mounted on the printed circuit board 1. The connector 130 may be installed to be subsequently removable from the printed circuit board. Referring to fig. 4, it can be seen that the connector 130 protrudes in the direction of one side (e.g., an upper surface, a lower surface, or a side portion) of the printed circuit board 1. In this case, the connector 130 may be formed to have a height at which the pin terminal can be easily inserted.

In the foregoing, the present invention has been described with reference to exemplary embodiments thereof, but it will be understood by those skilled in the art that various modifications and changes may be made thereto without departing from the spirit and scope of the present invention described in the appended claims.
